Chicken Cordon Bleu Lasagna

The idea hit me on a rainy Tuesday when I had leftover ham from Sunday dinner and a bundle of cooked chicken staring back from the fridge. Rather than make two separate meals, I layered everything into a lasagna format and crossed my fingers. The smell that filled my kitchen an hour later made me close my eyes and just breathe it in. That random experiment became the most requested dinner in my house.

My sister stopped by unannounced the second time I made this, and she stood in the kitchen doorway with her coat still on, waiting for a plate. We ended up sitting on the floor eating straight from the baking dish because nobody wanted to wait for it to be plated. She now texts me every fall asking when the cordon bleu lasagna is coming back.

Ingredients

• 3 cups cooked chicken breast, shredded or diced: Rotisserie chicken works beautifully here and saves you a step when you are short on time.
• 8 oz deli ham, thinly sliced: A good quality black forest ham adds a gentle smokiness that pairs perfectly with the Swiss.
• 2 cups shredded Swiss cheese: Do not skip the Swiss because its nutty melt is what makes this taste like true cordon bleu.
• 1 cup shredded mozzarella cheese: This gives you that irresistible golden stretch on top.
• 1/2 cup grated Parmesan cheese: A salty finish that crisps up beautifully in the final minutes of baking.
• 12 lasagna noodles: No boil noodles are a lifesaver but regular ones work just fine if cooked al dente.
• 3 tbsp unsalted butter: The start of your bechamel, so use fresh butter for the cleanest flavor.
• 3 tbsp all purpose flour: This creates the roux base that thickens your sauce.
• 3 cups whole milk: Whole milk makes the creamiest sauce, though two percent will do in a pinch.
• 2 tsp Dijon mustard: This is the secret ingredient that ties the whole cordon bleu concept together.
• 1/2 tsp garlic powder: Just enough to round out the flavors without overwhelming the delicate sauce.
• 1/2 tsp onion powder: Adds a subtle savory depth that people notice but cannot quite identify.
• 1/4 tsp black pepper: A gentle warmth that balances the richness of the cheeses.
• 1/2 tsp salt: Adjust to taste, especially if your ham is on the saltier side.
• 2 tbsp fresh parsley, chopped: A bright finishing touch that cuts through all that richness.

Instructions

Get your oven ready:

Preheat to 375 degrees and grease your 9x13 baking dish with butter so nothing sticks later.

Prep the noodles:

If using regular noodles, cook them until just al dente because they will soften more in the oven. Drain and lay them flat on a clean towel so they do not tear.

Build the bechamel:

Melt the butter in a saucepan over medium heat, then whisk in the flour and cook for one to two minutes until it smells lightly toasted. Pour in the milk slowly while whisking constantly to avoid lumps.

Season the sauce:

Once the sauce thickens enough to coat the back of a spoon, stir in the Dijon, garlic powder, onion powder, salt, and pepper. Remove from heat and taste it because this is your chance to adjust.

Start layering:

Spread a thin layer of sauce on the bottom of the dish to prevent sticking. Add noodles, then half the chicken, half the ham, and a third of the Swiss, followed by more sauce.

Build the second layer:

Repeat the same sequence with noodles, remaining chicken, remaining ham, more Swiss, and sauce. Press down gently so everything settles together nicely.

Create the golden top:

Finish with a final layer of noodles, the rest of the sauce, and all of the mozzarella and Parmesan. Make sure the cheese goes edge to edge for maximum crispiness.

Bake covered:

Cover tightly with foil and bake for 30 minutes so the layers meld together without drying out.

Finish uncovered:

Remove the foil and bake another 15 to 20 minutes until the top is deeply golden and bubbling at the edges.

Rest before slicing:

Let it sit for 10 minutes so the layers hold together when you cut. Sprinkle with fresh parsley and serve.

I brought this to a neighborhood potluck last winter and watched a man who never goes back for seconds return three times. His wife pulled me aside and whispered that she wanted the recipe before he ate the entire pan. That moment reminded me why I love cooking for people in the first place.

Making It Your Own

Swap the Swiss for Gruyere if you want something even richer and slightly earthier. Smoked turkey can stand in for the chicken when you want a different flavor profile without changing the spirit of the dish.

What to Serve Alongside

A crisp green salad with a bright vinaigrette cuts through the richness perfectly. A chilled glass of Chardonnay beside this lasagna turns a Tuesday dinner into something that feels like a special occasion.

Storage and Reheating

Leftovers keep well in the fridge for up to three days and actually taste better the next day when the flavors have had time to settle. Reheat individual portions in the oven at 350 degrees rather than the microwave so the top stays crispy instead of turning soggy.

• Cover the edges with foil if they start browning too quickly during reheating.
• Freeze individual portions wrapped tightly in foil for up to two months.
• Always let frozen portions thaw overnight in the fridge before reheating.

This lasagna is proof that some of the best meals come from throwing together what you already have and trusting your instincts. Make it once and it will become part of your permanent rotation.

Recipe Questions & Answers

→ Can I make this ahead of time?

Yes, assemble the entire dish up to 24 hours in advance, cover tightly, and refrigerate. Add 10-15 minutes to the baking time if baking cold from the refrigerator.

→ What type of chicken works best?

Rotisserie chicken or poached chicken breasts work well. The meat should be fully cooked and shredded or diced into bite-sized pieces before layering.

→ Can I substitute the ham?

Prosciutto, Black Forest ham, or even smoked turkey make excellent alternatives. Adjust quantities slightly if using more intensely flavored cured meats.

→ How do I prevent the noodles from getting soggy?

Ensure your béchamel is thick enough to coat the back of a spoon. Also, let the completed dish rest for 10 minutes before slicing to allow the layers to set.

→ What sides pair well with this dish?

A crisp green salad with vinaigrette balances the richness. Roasted vegetables like asparagus or green beans also complement the creamy flavors nicely.

→ Can I freeze leftovers?

Yes, individual portions freeze well for up to 3 months. Thaw overnight in the refrigerator and reheat covered at 350°F until warmed through.
